The temperature sensor monitors the actual process values whilst the heater is maintained at a constant differential temperature above this by varying the power consumed by the sensor.

8 The greater the mass flow, the greater the cooling effect and power required to maintain the differential temperature. The measured heater power is therefore a measure of the gas mass systemThe measuring system consists of a transmitter and a sensor. Two versions are available: Compact version: transmitter and sensor form a single mechanical unit. Remote version: transmitter and sensor are mounted physically separate from one 65a0003671 Two-line liquid-crystal display Configuration using push button operationSensorFa0005137 Flanged version Nominal diameters DN 15 to 100 ( " to 4") Sensor body material:- , 316L- CF3M Transducer body material.

Each meter is individually calibrated on air and mathematically converted to suit the customer specific gas, where table below defines the ranges available for air without flowconditioner.
